分析斜支承连续曲线箱梁桥时，采用考虑翘曲作用的曲线格子梁分析方法，应用矩阵位移法对具有约束支承形式的斜支承连续曲线薄壁箱梁桥进行分析，考虑到支座的约束条件并不与梁端弯曲角位移和扭转角位移的方向一致，引入支座节点坐标矩阵，使得梁端的位移未知量与斜支座约束方向一致，来计算单元刚度矩阵和单元节点力，然后按照矩阵位移法组集总刚并建立结构刚度方程，根据结构刚度方程即可求解未知的节点位移及杆端力，推导出任意截面处的内力计算公式。 - In the process , we import the displacement method " s concept of replacement ahead , that is to say , we replace the unknown vectors with new unknown vectors to prevent the delivering and accumulation of errors . at the same time , we completed the skew bridge calculation procedure , and compared the calculation results with the results by the finite element software ansys , it proved the correctness and practicality of this procedure
